b6059900a7 Disable warning C4291 on MSVC. Caused because class AttributeList provides a non implemented operator delete without a corresponding new.

028cf0619e On X86, MEMBARRIER, MFENCE, SFENCE, LFENCE are not target memory intrinsics, 
so don't claim they are.  They are allocated using DAG.getNode, so attempts
to access MemSDNode fields results in reading off the end of the allocated
memory.  This fixes crashes with "llc -debug" due to debug code trying to
print MemSDNode fields for these barrier nodes (since the crashes are not
deterministic, use valgrind to see this).  Add some nasty checking to try
to catch this kind of thing in the future.

3166f72d7a Removing the useless test that I added recently. It was meant as an example, but not complicated enough to merit another test.

de3ebc098a Detemplatize NodeRef. 
It is now possible to navigate the B+-tree using NodeRef::subtree() and
NodeRef::size() without knowing the key and value template types used in the
tree.

4a44e92fd1 Rename NodeBase::{key,val} as {first,second} and swap the BranchNode arrays such 
that the noderefs are the first member in the object.

This is in preparation of detemplatization of tree navigation.

Key and value objects may not be destructed instantly when they are erased from
the container, but they will be destructed eventually by the IntervalMap
destructor.

94babd312e When folding addressing modes in CodeGenPrepare, attempt to look through PHI nodes

unprofitable PRE transforms.
